BREAKING: You need to change your Facebook password right now. Facebook just disclosed that it stored hundreds of millions of user passwords for its platform and Instagram as plaintext in an internal platform. This means that thousands of Facebook employees could have searched for and found them.

Beginning Tuesday, when people decide to buy a product from a brand or retailer on Instagram, they’ll be able to pay for that product inside the app instead of leaving Instagram to finish the transaction on a retailer’s website. Instagram will keep a small cut of the sale for facilitating the purchase, and it’s partnering with PayPal to process the payments.
